    Classic Auto Air adapter mounting plate.

    As some may know, the CAA evap assembly is only intended for Non-A/C cars and it mounts off the OEM blower fan mounting holes.
    Well if you have an A/C car and want to upgrade your factory A/C box you're SOL. Why? because the blower fans are completely different between A/C and Non-A/C cars and there's just nothing left to mount the CAA evap box to.

    Well to solve this issue, I just measured the bejesus out of my stock and CAA evap and firewall and came up with this handy-dandy adapter plate. It has 1/4-20 studs that use 2 of the original stock evap mounting holes and has two open holes to emulate the Non-AC blower fan mounting so that the CAA evap had something to bolt to.

      You might want to make a full size tracing of that. Have you contacted the manufacturer to see if they're interested?

        Hi just found your post we are redoing my sons 72 Demon and he’s putting the classic air in it. My bad is I didn’t do my homework and we filled the factory air hose and painted the engine bay but I didn’t catch that the blower motors are different sizes so my question is how did your adapter plate turn out and do you sell them?any pictures of the final job done. Thanks for any help. KB9GIB
